snonn CONSUMER.

Application filed August 30, 1920. Serial No. 406,824.

To all whom it may. concern:

Be it known that I, FRANK H. DILLON, a citizen of the United States, residing at Rock lsland,.in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Smoke Consumers, of which the following is a specification.

My invention relates to improvements in devices for burning or consuming the smoke in steam boilers and furnaces and for economizing on fuel used therein, in which jets of air are introduced into the fire box above the level of the grate bars and the fuel thereon through curved pipes mounted at the sides of the boiler or furnace and extending into the combustion chamber from above, or in the case of boilers of the fire box type having water legs on each side of the fire chamber, the air pipes conduct the air into the fire chamber through draft tubes secured in the water legs of the boiler. j

The objects of my invention are; first, to provide means for regulating the amount of air introduced into the fire chamber which can be applied to the ordinary form of tubu-,

lar boilers, to water tube boilers and to fire box boilers including locomotive boilers having a water leg on each side of the fire cham-v ber or to any other form of boiler or furnace in which a down draft or horizontal draft of air is injected into the fire chamber by the use of steam, compressed air or other fluid; second, to provide positively operated means for closing the air draft for such boilers and furnaces operating independently of the steam or compressed air valves.

I attain these objects by themechanism illustrated in the accompanying drawings, in which Figure 1 is a front elevation of a boiler furnace with my device applied thereto. the righthand side of the drawing showing boiler furnace with the front plate and air valves removed.

Figure 2 is a plan view of my device as shown in Figure 1, but showing the left middle manifold in section on the line 0000 of Figure 1 with the steam jets and air valves removed, and the right middle manifold in section on the line was of Figure 1.

Figure 3 is a sectional elevation of my device applied to a firebox boiler of the water leg type with bricked-in installation.

Figure 4 is a side elevation of my device showing air tubes, stationary and movable plates in dotted lines in the left portion of the figure and showing the right portion of the figure in section.

Figure 5 is a sectional detail of the air valves, etc.

Similar numerals refer to similar parts throughout the several views.

Air tubes, 2, are provided at each side of the ordinary tubular boilers as in Figure 1 or air tubes, 21, as shown in Figure 3. The upper ends of these air tubes are slightly enlarged to seat in bosses, 4", formed in a sta tionary plate, 4, which is mounted upon the brickwork of the ordinary bricked-in boiler installation or suitably secured at the desired height by any of the well-known means in the case of other boilers. This stationary plate is provided with a series of circular openings, 4, corresponding to the interior of the tubes, 2 and 21. Similar openings, 10", are formed in the movable plate, 10, which is slidingly mounted upon the stationary plate, 4, in such a way as to slide longitudinally and secured in place by gravity, or any other desired means.

An air admission manifold, 3, is secured to the sliding plate 10, so as to slide with the plate, 10. Steam jets, 7, are secured in the top of the manifold, 3, and may also be additionally secured by brackets, 9, riveted or bolted to the sliding plate, 10. Each jet, 7 is provided with an air valve, 8, mounted thereon which is secured to the jet by a set screw, 8 passing through a collar, 8*, or by any other suitable means which will allow the valve, 8, to be adjusted vertically upon the jet, 7. The upper ends of the jets are secured to and open into a supply pipe 5, which may be one continuous pipe or sections of pipe connected by Ts, 6, as in Figure 4.

The pipe, 5, is supplied with steam through the pipe, 19, which may be connected with the boilers in any suitable way, by intermediate pipes, 14 and 15. Valves, 16 and 17, are provided by which the steam supply may be shut off from the steam pipes on either side; and the valve, 18 is provided tions may be used to connect pipe, 14, with pipe, 15.

I make no claim for any particular form .offlexible or movable connection, as these are well-known and in common use.

The manifold, 3, ispreferably left open at the rear end, but the opening may be at either end or at the side or top without departing from the spirit of my invention.

In Figure 2 an air opening, 3, is shown in the top of the manifold.

When applied to water tube boilers, the air may be introduced into the fire chamber inside the furnace walls as in Figure 1, or through a water leg as in Figure 3, or the air pipes may be mounted outside the furnace walls and extended through the furnace walls similarly to the arrangement shown iii-Figure 3, consideringthe furnace Walls substituted for the water leg, 26.

The sliding plate, 10, is connected at one end by a suitable yoke, 11*, and connecting rod, 11, to one end of a lever, 12, fulcrumed at 13, in any suitable support, 13, and the other end of the lever forms a handle,12, by which same canbe manually. operated.

, The sliding plate, 10, and manifold, 3, can

be movedlongitudinally upon the stationary plate, 4,,far enough to move the openings, 10%, out of juxtaposition with the openings, so that the intermediate portions of the slidingplate, 10, will securely closethe upper end of the air tubes, 2 or 21.

In the operation of my device, the fires are built under the boilers in the usual way. As soon as sufficient steam pressure has been raised, steam may be turnedinto the pipes, 15, and passing out through the j ets, 7 will carry air downward into the pipes, 2 or 21, as the case may be. This air will pass through the lower ends of the pipes, 2 or 21, into the firev chamber. The lower ends of the tubes, 2, are preferably curved inward to direct the stream of air somewhat toward the middle of the grates as well as downward and the same result as obtained'by the nozzle, 25, shown in Figure 3.

vIn batteries of boilers, of course steam may be used from one boiler to assist in firing. up 1 other boilers.

In practice, a steam pressure of five pounds or upward will be found suflicient to operate my device effectively.

' In practice,- I find it isadvisable to have means for positively closing entirely the upper ends of the air tubes. Even though the steam or compressed air is entirely shut off, if the air tubes are not thus closed, there will be a heavy inrush of air through them on account of the natural stack draft and 7116111 building, afire before any draft is established, it is sometimes necessary to close the upper ends of the air tubes to prevent smoke escaping fromthe furnace into the boiler room.

In practice, a very light steam pressure in the jets, 7, is sufficient to carry an ample supply of'air to the'fire chamber and it is necessary to provide means by which the supply of air can be limited while the air tubes 2I'and 21 are left entirely open. In the smoke consumers heretofore in" use, no provision has'been' made foradjustin the air supply except by limiting the supp y of steam or sliding the plates and there is always a likelihood that t-heste'amjets would be open too far so that too much air would be drawn intothe tubes or'the sliding plate would be moved in sucha positionasto prevent the entrance of the steam directly, into the upper ends of the air tubes.

In'my device, the air regulating v'zrlve prevents the admission of too much air even th'oughthe steam jet is opened wider than intended and ample'mea'ns are provided for entirely closing the. air tubes when desired.

The manifold, 3, may be built integral or with one side removable to allow access to the" jets and regulating valres secured therein.
